Abstract:

This talk describes one of the major efforts in the sensor network 
community to build an integrated sensor network system for energy 
efficient surveillance. The focus of this effort is to acquire and 
verify information about enemy capabilities and positions of hostile 
targets. Such missions often involve a high element of risk for human 
personnel and require a high degree of stealthiness. Hence, the ability 
to deploy unmanned surveillance missions, by using wireless sensor 
networks, is of great practical importance for the military. Because of 
the energy constraints of sensor devices, such systems necessitate an 
integrated energy-aware design to ensure the longevity of surveillance 
missions. In this talk, we describe the design and implementation of an 
integrated running system, called VigilNet, for energy-efficient 
surveillance. The VigilNet allows a group of cooperating sensor devices 
to detect and track the positions of moving vehicles/personnels in an 
energy-efficient, responsive, robust and stealthy manner. VigilNet 
integrates over 30 protocols and consists about 40,000 lines of NesC and 
Java code, running on XSM, Mica2 and Mica2dot platforms. It has been 
recently successfully transferred and classified for realistic military 
deployment.
